ABSTRACT:
A method for controlling the supercharge pressure in an internal combustion engine having a mechanical supercharger which is connected to the crankshaft in the engine and in which the internal compression ratio of the supercharger can be varied. In the method, the internal compression ratio of the mechanical supercharge is varied on the basis of at least a preset supercharge pressure and an engine revolution rate. This ensures that the supercharge pressure can be matched with the internal compression ratio to prevent a pulsing, thereby preventing noise from being generated.
